Synthesis and characterization of microporous layered zirconium phenylphosphonate

Microporous layered zirconium phenylphosphonate, Zr(O₃P-C ₆H₅)₂ was prepared in presence of sodium dodecylsulfate (SDS), for the first time. Interplanar spacing (d₀₀₁) and surface area of microporous zirconium phenylphosphonate are 1.47 nm and 198 m²g^-1, respectively. FT-IR spectrum indicates absence or negligible amount of hydroxyls groups in zirconium phenylphosphonate sample, ³¹P solid MAS NMR also confirms the presence of trace amount of hydroxyl groups in zirconium phenylphosphonate. The presence of tetra-coordinated phosphorous ions and hexa-coordinated zirconium ions were realized by the ³¹P solid MAS NMR and UV-visible, respectively. Sulfonated derivative of zirconium phenylphosphonate, Zr(O₃PC ₆H₄SO₃H)₁₉ (O₃PC ₆H₅)_0.1·3.7H₂O were also prepared.
